| Food recalls are important for two reasons. One is that they mitigate harm when product failures occur. Another is that they augment incentives to invest in safety. When recalls are justified for their mitigation value, it makes sense that regulatory bodies be granted more control of the recall process in order to improve the manner in which recalls are conducted. Such is the stated intent of most proposals for changing the food recall system. However, we show that recalls can be justified by their incentive effect alone. In fact, recalls can be beneficial even when the social value of the harm they mitigate is so small as to be less than the costs of carrying them out. In these cases, it is important that proposals designed to improve the recall... |

| We examine the role of peer effects in childhood obesity outcomes by investigating whether obesity rates among the highest graders in a public school has an effect on obesity rates among younger grades. We use a panel dataset with obesity prevalence measured at the grade level. Our data are from Arkansas public schools. Results provide evidence that changes in the obesity prevalence at the highest grade are associated with changes in obesity prevalence at younger grades. The magnitude of the peer effect depends on the type of school, and we find statistically significant peer effects in both elementary and high schools but not in middle schools. These effects are also larger in high schools than in elementary schools. We use falsification tests to provide... |

| The number and volume of meat and poultry recalls has increased substantially in recent years. This is likely due to regulatory emphasis on foodborne illness resulting in an increased frequency of testing for pathogens. We use an equilibrium-displacement model to examine the effects of recall costs on the beef, pork, and poultry industries. Results suggest that higher recall costs may have actually increased producer surplus to the broiler industry because of consumer substitution among products and that most losses resulting from recalls are accruing to the beef and pork industries. |

| Using an event study, we examine the impact of recalls for E. Coli O157:H7 on wholesale and farm-level beef prices. Prices for boneless beef, a high-volume product primarily used for processing into ground beef, react negatively to recalls, suggesting incentives exist for packing firms to adopt measures that reduce the risk of contamination. However, there is no reaction in live cattle prices and very little reaction in boxed beef prices to recall events. This suggests short-run price responses found at the wholesale level for boneless beef do not transmit back to the farm level. |

| Consolidation has been a trend among local cooperatives for most of the past century. Earlier studies show that these cooperatives face size-related economies and that consolidation is to be expected as cooperatives seek to improve their efficiency and competitiveness. In this article we revisit the question using data from 377 local cooperative associations in operation during the 1990s. Methods involve using nonparametric cost frontiers that enable us to distinguish the effects of scale inefficiency from other production inefficiencies. Our results suggest that many local cooperatives are at or near an efficient scale of operation. |
